curves on a two-lane road It has a radius of 400 meters and is
designed using a design speed of 90 kilometers per hour.
with a curve contact distance of 175 meters and the Pl point is at
STA. 10+000 if the road has a traffic lane 3.5 meters wide
The coefficient of friction of the road during rain is 0.12 and the
slope behind the road (Crown slope) is 2%.
Calculate and design for the difference of STA. at points NC, HC,
FC, FS (both Attained and Ramoved sections), PC and PT points for
raising a flat curve by using the center line rotation
method.
S = 75+1.5V(Km/hr)
Ts = X+Y+Z
